Is it tripping a MCB, a RCBO or the RCD?

10mm seems fine providing its not wrapped in insulation!!!

suggest getting a Sparky out to check supply!

Check continuity and insulation resistance readings.

i always love the old........'i have a friend' post!

 

[Wolfman]

It's an mcb and it's not wrapped in insulation

I second Pushrod suggestion!

 

[telectrix]

as per pushrod. if readings are acceptable. clamp meter , measure current. possible faulty shower unit. is it made in china

Get an electrician in to test it. You, sorry you don't want your friend getting in the shower with a fault up to 50amp. Break dancing naked in the bath tub is never a good idea.

Firstly i would point out this work is notifiable under part P , If it trips the MCB there is a possability that the shower may have been wired incorrectly , check all connections and that the right back box patress has been used 47mm especially in the switch as wiring 10mm into the switches can be a right pain ,, but if in doubt call a spark

Don't forget to check the isolation switch too, IR on the cable back to the CU and IR on the cable to the shower.

Probably wouldnt apply to Holly Willoughby if I was in the same room.

I think I've found my feet in the forum. I could have put:-

"Your friend" is fine the way this is wired up as long as he is standing on a rubber bath mat. OR "your friend is fine" if he calls the local water board and requests that his water supply is de-minaralised so electric current can not be conducted whilst using dove shower gel. OR :- £50 for an electrician or £3000 for a funeral. The choice is yours gentleman.
